My wife and I checked out the Tanana for burbot this weekend, just a day or two after the Nenana Ice Classic tripod fell, indicating that the ice went out about fifty miles downstream. We found no sign of fish at the first spot we tried, which had open water with ice chunks floating around. At the second spot, we caught the ice break-up in action--a spectacular show to watch.
The last contiguous ice on the Tanana near town. On the right side of the photo, the river's original ice still extends all the way across. A rapid flow of water and ice is pushing in toward it from the left. Moments later, the original ice gave way and opened up a free-flowing channel packed with truck-sized icebergs.
Lake Ontario's post-breakup could be exciting some years. Ah! And I remember the first time I heard big lakes "making ice". A long way from shore, sitting on a bucket, and BA-BOOM! Sounding like thunder. I'd stand up -fast!- and look all around with my heart pounding, half expecting a Kraken to take me to see Davy Jones. But after having drilled through over 2ft of ice, I knew that wasn't likely. But my adrenals weren't so sure!
